Identifying the Issue

Computer with a missing CD/DVD drive icon

To identify the issue of a disappeared CD/DVD Rom drive in Windows 7, begin by checking the Device Manager to see if the drive is listed. If it is not showing up, it may be a driver issue. Update the device driver by right-clicking on the drive in Device Manager, selecting “Update driver,” and following the on-screen instructions.

If updating the driver does not resolve the issue, check the Windows Registry for any corruption or missing entries related to the CD/DVD drive. To do this, press the Windows key + R, type “regedit,” and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}. Delete the “UpperFilters” and “LowerFilters” entries if they exist, then restart your computer.

If the drive still does not appear, it may be a hardware issue. Check the BIOS settings to ensure the drive is detected during boot. Restart your computer and press the key (usually F2 or Delete) to enter the BIOS setup. Look for the CD/DVD drive in the list of connected devices and make sure it is enabled.

Reinstalling Drivers

To reinstall drivers for your CD/DVD ROM drive on Windows 7, follow these steps:

First, open the Device Manager by pressing the Windows key + R, typing “devmgmt.msc” into the Run dialog box, and hitting Enter.

In the Device Manager window, locate the CD/DVD ROM drive under the DVD/CD-ROM drives category.

Right-click on the CD/DVD ROM drive and select “Uninstall device” from the context menu.

After uninstalling the device, restart your computer.

Once your computer has restarted, Windows 7 should automatically reinstall the drivers for the CD/DVD ROM drive.

If the drivers are not automatically reinstalled, you can manually reinstall them by downloading the latest drivers from the manufacturer’s website and running the installer.

After reinstalling the drivers, restart your computer again to complete the process.

Your CD/DVD ROM drive should now reappear in File Explorer and be ready to use.
